FASTENER FOR MEETING-RAILS' OF SASHES.

SIPEGIF'ICATIONI forming part of Letters Patent No. 550,221, dated November 19, 1895. Application filed Tilly 18, 1895. Serial No. 556,365. (No model.)

Yf--btate of Connecticut, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification.

The object of my invention is to provide an improved fastener for securing the meet- `ing-rails of the upper and lower sashes, both for preventing the opening of the window an'dto secure them against rattling, as hereinafterl described,.reference being made to the accompanying drawings, in which- Figure 1 is an elevation of a window with my improved sash-fastener applied. Fig. 2 is a transverse section of the meeting-rails, showing the fastener in side view, with a part in section and enlarged and showing the sashes fastened together. Fig. 3 is a part of Fig. 2 in-the'same view detached from the rest of the parts of said figure. Fig. 4 is a section on the line .fr of Fig. 2. Fig. 5 is a section on line y y of Fig. 2. Fig. 6 is a section on lin' z of Fig. 2. Fig. 7 is a section like Fig. 2, but showing the sashes unfastened. Figs. 8, 9, and 10 represent the fastening-bolt in different side views. Fig. 11 is a side view of the fastening-bolt and a section of the knob-sleeve for working the bolt, and Fig. 12 is a side view of the bolt and said sleeve.

The meeting-rail a of the upper sash has a socket b in the face fronting the meetingrail c of the .lower sash, into which socket the bolt d, carried by the meeting-rail c of the lower sash, projects for connecting the two rails .to prevent opening the window, and a catch-lip eis fixed in the mouth of the socket, behind which a hook-bit f on the extremity of the bolt is made to engage after the bolt has been thrust inthe socket to bind the two sashes together to prevent rattling. The catch-lip e projects ,inward from one side of the socket a suitable extent for being engaged by the hook-bit f, and the bolt is recessed on one side, as shown at g, to pass over the catchlip. The end of the bolt is beveled at h to facilitate entering the socket.

The meeting-rail c is bored to receive the bolt d, said bolt being partly incased in the bore of the rail and partly in the sleeve, and said rail is counterbored for reception of a sleeved for working it, and also counterbored for reception of a collar j of the knob 7c, to which the sleeve t' is attached for being operated by the knob, said collar being retained by the escutcheon-plate Z, screwed onto the inside face of meeting-rail' c.

The sleeve e' has spiral grooves m, and the bolt has studsn engaging said grooves to slide the bolt forward and backward for locking and unlocking the sashes.

The bolt has a longitudinal groove o, with which a lateral or circumferential branch groove p connects at the forward extremity, in which a stud q, set in the wall of the bore in the sash for the bolt, engages, the part o of said groove being to prevent the bolt from being turned by the sleeve while shifting the bolt forward and backward, and the branch p being to permit the bolt to be turned after being thrust forward to lock the meeting-rails vtogether by the catch-lip e and the hook-bit f, said branch being in the relation to stud q whereby it registers with said stud when the bolt is in the forward position, and permits the turning of the bolt by the sleeve and the studs n, the latter bing then at one end of the slots fm, respectively, as seen in Fig. 2, and subject to be turned by the sleeve, the movement of which is to be continued in the same direction as for thrusting the bolt forward until stopped by the lodgment of the Vbottom of the branch groove p against the stud q. Reverse movement of the knob will first cau se rotation of the bolt for releasing the catch-lip and hook-bit,'and will return groove 0 to line with the studq, whichA will stop further movement in the reverse direction, and then the spiral grooves m, acting on the studs n, will withdraw the bolt and unfasten the sashes, as seen in Fig. 7.

V While I prefer the arrangement of the socket and the catch-lip in the face of the meeting-rail of the upper sash and the bolt and its operating sleeve in a bore of the meeting-rail of the lower sash, as represented in the drawings, I do not mean to limit myself to such arrangement, for they may be located in attachments adapted to be placed on the upper sides of the meeting-rails, respect- IOO iVely, whieh is within the scope of my invention.

I claim- 1. The combination with the upper sash having the eatolvlip 011 its meeting rail, of the slide bolt and rota-ting knob sleeve on the meeting rail of the lower sash, said sleeve having the spiral slots, and the Slide bolt arranged partly in the bore of the sleeve, and partly in another oase, and having the studs engagingsaid slots of the sleeve for thrusting the bolt bythe rotation of the sleeveyand the stud in the bolt ease and groove in the bolt for holding the bolt during rotation of the sleeve for effecting lengthwise movement of the bolt by the sleeve substantially as described.

2. The combina-tion with the upper sash having the Catch-lip on its meeting rail, of the slide bolt and the spirally slotted rotating turn it rotatively by the sleeve for looking 3o and unlocking the sash substantially as described.
